The trick is a \"Token Schema\" that organizes the three channels without requiring any changes to the model's architecture, paired with training data built from synthesized per-second annotations. On benchmark tests, LWS scored 4.72 on VoiceBench AlpacaEval and hit 92.6% consistency between what it wrote and what it said out loud. It also beat its own stripped-down versions on URO-Bench and performed well on Full-Duplex-Bench, a test of real-time back-and-forth conversation.\n\nThe catch with voice assistants has always been that speech can't easily carry code, tables, or multi-step reasoning - you can't dictate a working Python function over the phone. By making text a first-class output alongside audio, LWS lets a spoken assistant show its work: a block of code, a structured comparison, a chain of reasoning, while still replying out loud without a lag. That's a real gap for anyone using voice interfaces for anything more technical than a to-do list.\n\nWhether this becomes the standard architecture for voice assistants or stays a research paper is the open question - plenty of promising full-duplex tricks never leave the benchmark stage.","[\"ai\",\"speech-ai\",\"llm\",\"research\"]","2026-09-16T04:00:00.000Z","2026-09-17T18:21:44.896Z","2026-09-17T18:21:56.779Z","published",null,[],"ai",[24,26,27,28],"speech-ai","llm","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.07547",0,{"sections":35},[36,40,45,50,55,59,63,68,73,77,82,87,92,97],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3852,"2026-09-17T08:27:09.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",648,"2026-09-17T04:00:00.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",338,"2026-09-11T04:00:00.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":44},"Hardware","hardware",154,{"name":60,"slug":61,"count":62,"latest_published_at":44},"Science","science",114,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":44},"Dev Tools","dev-tools",73,{"name":78,"slug":79,"count":80,"latest_published_at":81},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
